A pretty simple Garry's Mod map. It's a large maze made up of a grid of squares, each with 4 walls. The walls will move up and down randomly, changing the shape of the maze. There's a catwalk at the end, from which you can shoot down or lob grenades at the players below you. There's also 2 buttons at the end, one to lower all the walls, and one to invert them all.
